SparkFun Qwiic HAT for Raspberry Pi

The kit includes 20 basic sensors, which will help you to easily kick-start any project. The sensors are featured with a proprietary Seeed Grove connectors enabling easy connection without soldering and a comprehensive guide book with exemplary classes.

This little board is simply a I2C board to Qwiic converter. It pretty much enables any device with I2C connectors to work with Qwiic system. It has two Qwiic ports - both of them served with the same I2C bus. You simply stick the board on your I2C board and get additional two Qwiic ports. It is as easy as it sounds

This touch HAT for Raspberry Pi will inspire your next interactive project with up to 12 capacitive touch sensors, from fruit keyboards to interactive lighting.

16 servo motors with one board seems impossible? With this board not only it isn´t impossible, but it even seems easy. Additionally, you won´t need to sacrifice any of your valuable GPIOs as the HAT connects directly via I2C. Additionally, you have a serial terminal connection at your disposal.

You can supply the power to the board through your Pi or directly if you are going for larger servos and would need a separate source of power. Simply scrap a small blob of solder on the isolation jumper.

Seeed Grove Arduino Starter kit is a game-changer for schools and robotic classes. You get a set of 10 sensors with a Arduino compatible board and 12 classes for only 28.99 EUR!

This module is used to extend the Raspberry's 40 GPIO pins to another set of 2x20 male pins and 8 parallel pins accessible on the terminal blocks in the that test leads are pushed. The electronic board offers great reliability with the Raspberry and is very easy to connect thanks to its existing suitable accessories but not included.
The module offers a set of mini jumpers to configure the GPIO.

This tiny little board features two chips from Maxim Integrated: MAX32664 and MAX30101. The 30101 Oximetry module  is the sensor on board responding for both oximetry and heart rate sesnsing. The MAX32664 is equipped with a Cortex M4 handling algorithimc calculations, digital filtering and automatic gain control. The board comes with I2C and SparkFun has provided to it Qwiic connectors for ease of use.

This Serial Expansion HAT provides a 2-channel I2C and UART interface with 8 programmable GPIO Pins where you can connect more accessories and add-ons.
